The J-H(ST)H 2X2X0,6 Bd grey is a halogen-free installation cable from manufacturer VDE-Kabel, specifically designed for use in telecommunication and information processing systems. It is used for the transmission of telephone, measurement, and signal information, as well as in telephone station and PBX installations for telecommunication systems of all classes. The cable is suitable for use in dry and damp operating environments and can be installed on, in, and under plaster. Its static screen ensures reliable limitation of external electromagnetic interference fields, improving signal quality in electrically noisy environments. In the event of fire, the cable exhibits improved performance: no fire-related damage occurs due to halogen-containing gases, smoke development is low, and no corrosive gases are released.

Applications
This cable is intended for use in buildings with high requirements for fire safety and signal integrity. It is used in office buildings, administrative buildings, industrial facilities, and other installations where telecommunication and information processing systems are installed. Installation in indoor spaces, including within walls, ceilings, and under plaster, is permitted. The halogen-free design makes it particularly suitable for rooms where smoke development and the formation of toxic gases must be minimized in the event of fire.

Functions and Equipment in Detail
The cable consists of bare, single-strand copper conductors with a diameter of 0.6 mm. Each conductor is insulated with cross-linked polymer HI1 according to VDE 0207 Part 23. Conductor identification follows VDE 0815. The conductors are twisted into star quads, with five star quads assembled into a bundle. The bundle is laid in layers and taped. The static screen consists of a plastic-laminated metal foil, with the metal side facing inward, and a bare twin wire. The outer sheath is made of a polyolefin blend HM2 according to VDE 0207 Part 24, halogen-free and flame-retardant. The sheath color is grey, corresponding to RAL 7001.

Technology Explained Simply
The rated voltage is 300 V, with a test voltage of 800 V. The loop resistance is 130 Ohm/km, typical for a cable with a 0.6 mm conductor diameter. The current-carrying capacity is 2.5 A, and the operating capacitance is 120 nF/km. The insulation resistance is 100 MOhm x km. The capacitive coupling K1 is 300 pF, and K9-12 is 100 pF (measured over 100 m at 800 Hz). The cable attenuation is approximately 1.7 dB/km (at 800 Hz). The temperature range is from -5 °C to +50 °C, with a maximum operating temperature of +70 °C. The bending radius is 7.5 times the cable diameter for normal bending and 2.5 times for single bending without tension. The burning behavior corresponds to test method C according to VDE 0472 Part 804 (equivalent to IEC 332-1), indicating low flame spread and limited flame front.

Compatibility and Accessories
The cable is designed for use in telecommunication and information processing systems and can be connected using standard connection and plug technology. Its use in systems aligned with VDE 0207 and VDE 0472 standards is intended. The cable is not specifically designed for PoE (Power over Ethernet) applications, as the current-carrying capacity and cable attenuation are insufficient for such uses.

Installation and Mounting
The cable can be installed indoors on, in, and under plaster. During installation, the specified bending radius of 7.5 times the cable diameter must be observed to avoid mechanical damage. For single bending without tension, a bending radius of 2.5 times the cable diameter may be used. Installation typically occurs in cable ducts, walls, or ceilings, taking into account electrical and mechanical loads.

Operational Advantages
The halogen-free design of the cable reduces the formation of toxic gases and minimizes smoke development in the event of fire, facilitating evacuation and firefighting. The static screen provides high resistance to interference, enhancing signal quality in electrically noisy environments. The flame-retardant properties of the cable prevent rapid fire spread. The cable is suitable for use in dry and damp rooms, making it applicable in a wide range of indoor installations. The use of cross-linked polymer as insulating material ensures high mechanical and thermal stability.
